The facade of the building consists of a lattice made of full and empty cubes. During the day, sunlight on the porous shell of the library building creates shadow lights dramatizing and emphasizing the shape and depth of the volumes. This lighting design also helps recreate the facade at night. For this purpose, the volume of each cube is illuminated separately using light sources while ensuring a cohesive façade design. Selecting light sources with a suitable angle to prevent burning the cubes has been one of the important points in lighting of the facade of this building. In order to create a spectrum of light in the vertical direction of the building, the cubes are lit in 4 double groups and a separate row, with 5 different light color temperatures(2000, 2500, 2700, 3000, 4000k). Warmer light colors are utilized to induce heavier weight at the bottom of the facade and colder color lights are used in the upper parts of the facade.
